Stereo VideoMic
The SVM is destined to become an Industry standard and not
only offers the same sound quality & performance as it’s
predecessor (VM) but also meets the industry demand for
stereo recording. The X/Y configuration enables the SVM to
capture the true ambience of the recording space, while still
offering a high level of rear rejection and low noise. Powered
by a standard 9v battery, the SVM also offers a power status
LED, a high pass filter switch and pad to match most cameras
imputs. The SVM incorporates a custom shock mount system
and comes completed with a high level wind filter.
Features
• Stereo X/Y condenser microphone.
• Broadcast sound quality.
• Rugged cast aluminum body.

There are three switches
located on the end of the mic
body (fig. 8):a Pad (with 0 and
-10dB level cut), an On-Off
switch, a High Pass Filter (
and ) with which you
can use to remove rumble or
other low frequency noise while
recording. It will affect the tone
slightly but in some situations it
is required.
A power indicator LED flashes
RED for 0.25 sec. when the mic
is first turned on.
This changes to GREEN indicat-
ing the battery has adequate
charge. When the battery runs
low, the LED will change back
to RED and you should change
the battery for a fresh one.performance.
